SPECIFICATION forming part of Letters Patent No. 764,476, dated July 5, 1904.

Application filed April 19, 1904. Serial No. 203,890. (No model.)

. .'Zo @ZZ whom it may concern:

Be it known that I, Vieron KoUNs, a `citizen of the United States, and a resident of Mokane, in the county of Callaway and State of lVIissouri, have invented a new and Improved Dumping-Oar, of which the following is a full, clear, and exact description.

This invention relates to improvements in side-dumping cars, the object being' to provide a means whereby all of the cars in a train may be simultaneously dumped,the dumping mechanism being operated from the locomotive, thus resulting in a saving of time in discharging train-loads.

I will describe a dumping-car embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, 1n which similar characters of reference lndicate corresponding parts in all the iigures. p Figure 1 1s a transverse sectional view of a dumping-car embodyingl my invention. Fig;` 2 is a section on the line a' of Fig. 1. Fig. 3

single point, as will be hereinafter described.

Referring to the drawings, 1 designates the truck of a car, having standards 2 at the ends, with which the platform 3 has swinging connection. As here shown, the platform has on its under side a central beam 4:, from which trunnions 5 extend into the standards 2. Arranged underneath the platform is a rocleshaft 6, on the ends of which are dump-actuating wheels 7. Each dumping-wheel for a portion of its circumference has a peripheral channel, andthe side walls of the channel are provided with notches 8 to receive a block or ball 9, carried by` chains 10, and each wheel 7 is also provided with antifriction -rollers l1. As

here shown there are four antifrietion-rollers in each wheel; but the number may be varied Without departing from the spirit of my invention. The chains 1() have spring yielding connections 12 with the platform 3 near the sides, and the said chains pass underneath rollers 13, mounted in the truck-frame. The dump-controlling wheels 7 are provided with projections or lugs lil, designed to engage between latch plates 15 16, pivoted at their upper ends between straps 17 and the frame portions of the truck. The upper portions at the inner sides of theselatches are curved, and their top ends are curved or cam-shaped. The latches .15 16 of a pair are connected by a spring 18, and the latches are movable between the frame-truck and guide-plates 19. To prevent the wheels 7 from moving too far, I employ stops 71L at opposite sides for engaging with the lugs 14.

Arranged underneath the rock-shaft 6 is a `shifting shaft 20, which has bearings in hangers 21, attached to cross-bars 22, and also has a bearing in a standard 23. At the ends the shaft 2() has downwardly-extended arms 24, carrying rollers 25, which engage between the lower ends of the latches l5 16, and at about the center of the shaft 20 is a downwardly?` extended arm 26, the lower end of which" moves between plates 27 28,.secured to a crossbar 29. These plates are provided with perforations at opposite sides of the arm 26, so that a locking-pin 3() may be placed in the perforations at one side of the arm, depending upon the direction the platform is to be dumped. In fact, when the train is moving with the load pinsmay be placed at each side of the arm, so as to hold the shaft 2O rigidly in position.

A coiled spring 3l is connected at one end to the shaft 20 and at the other end to a crank member 32 formed in the shaft 6. This spring 31 serves to yieldingly hold the roclcshaft in its released position when the platform is in dumping position and with a lug 14 in engagement with a latch 7, so that the ball 9 will readily enter the notch 8 for returning the platform to normal position.

From a winding-drum 33, supported on a truck 34, attached to the locomotive 35, operating-cables 36 37 extend along opposite sides of the several cars and underneath the platforms. These cables are reversely wound on the drum, so that when operating' the drum to dump the several car-platforms in one direction the cable on the opposite side will be wound on the drum, keeping the same taut. The drum is operated by an engine 38, which receives steam from the locomotive.

The cables engage with pulleys 39, supported on the truck 1 at the lower portion and at the ends, and then pass around pulleys 40, carried by the truck, thence through pulleys 41, attached to the platform 3, and around pulleys 42, attached to the arm 26. At the rear ends the cables have spring yielding' connection 43 with the rear end of the rear car, thus providing' cushions to 'prevent possible breaking of the cables when sudden strain is given to the same. The sections of the cables between the cars are protected from dirt, stones, or the like by means of platforms 44, each platform being hinged to the rear end of a car and designed to engage with a part of the truck of the car immediately in the rear, as clearly illustrated in Fig. 7.

In coupling the cars of a train the coupling links and pins should be made very strong, so as to reduce possibility or danger of breaking the train apart, and it may be here stated that with my improved method of dumping the several cars of a train the cars may be kept connected for any desired length of time. It may be further stated that the train is moved by either a pushing or pulling operation of the locomotive, as may be desired, and the cables may be adjusted as to length of train by setting the brake on the end car and straining or stretching' the train to its full length and then adjusting the cables accordingly before the train is started on its journey.

q In the operation when it is desired to dump `a train-load the brake is again set and the train stretched and the pins 30 are to be removed at the side opposite the direction in which the platforms are to be tilted, provided such pins are in their places. Then by operating the drum 33 in the proper direction the cable at the dumping side will be drawn taut, while the cable at the other side is paid off the drum. The cable at the 'dumping side will rock the shaft 20, causing the arms 24 to swing the latch 15 or 16, as the case may be, to release it from the projection 14, permitting the chains lO to be operated by means of the wheels 7 to tilt the platform. After dumping it is obvious that a reverse motion of the drum will shift the several platforms to normal position and also shift the arms 26 into latching position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A plurality of connected dumping-cars,

means for holding the car-platforms in horizontal position, and mechanism for simultaneously releasing the holding devices and dumping all of the cars.

2. A plurality of connected cars, each car having a side-tilting platform, a rock-shaft supported in each car, dump -controlling wheels mounted on said shaft, the said wheels being notched in the periphery, chains ex-v tended over said wheels and having blocks for engaging in the notches, pulleys on the truck of the car around which the chains pass, the ends of said chains being connected to the platform near the sides, means for locking the wheels in normal position, means for releasing the locking' devices, and cables extended along the several cars of a train and adapted for operation to dump the several cars simultaneously.

3.
